DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Figure 1-3 As shown, the utility model provides a power cable cutter, including a workbench 2, an arched bracket 4 is arranged in the middle of the upper surface of the workbench 2, two roller grooves 12 are symmetrically opened on the left and right sides of the arched bracket 4, a lower roller 8 is rotatably connected to the lower end of the arched bracket 4, a length meter 5 for measuring the length of the power cable is arranged on the outer surface of one side of the arched bracket 4, a side of the lower roller 8 close to the length meter passes through the arched bracket 4, and is connected to the rotating end of the length meter 5, a lifting bracket 18 is sleeved in the roller groove 12, and the lower end of the lifting bracket 18 is rotatably connected to the upper roller 9.

[0023] By adopting the above technical solution, the arch bracket 4 fixes the height of the lower roller 8, and the upper roller 9 can move up and down along the roller groove 12 with the lifting bracket 18, so as to adapt to the cutting of cables with different diameters. The lower roller 8 is rotatably connected to the length meter 5, and the length meter 5 can indirectly calculate the length of the cable passing through by the number of rolling circles of the lower roller 8.

[0024] The upper end of the lifting bracket 18 passes through the top of the arch bracket 4 , and the lower end of the lifting bracket 18 is located at the top of the arch bracket 4 and is provided with a spring 10 . The top of the lifting bracket 18 is fixedly installed with a hand pull ring 11 .

[0025] By adopting the above technical solution, the upper roller 9 can be moved upward by pulling the hand pull ring 11 upward. When the cable passes through, the spring 10 presses the upper roller 9 downward so that the upper roller 9 and the lower roller 8 are in contact with the cable.

[0026] A knife groove 7 is provided on one side of the upper surface of the workbench 2, a cable cutting groove 17 is provided at the middle end of the knife groove 7, an inverted L bracket 15 is provided on one side of the rear side of the workbench 2, and a crank pull rod 13 is rotatably connected to one side of the top of the inverted L bracket 15.

[0027] The middle bending part of the crank pull rod 13 is rotatably connected to the upper end of the arc-shaped transmission block 14 through a rotating rod. The side of the arc-shaped transmission block 14 away from the crank pull rod 13 is rotatably connected to an arc-shaped knife 16. The side of the arc-shaped knife 16 away from the arc-shaped transmission block 14 is rotatably connected to the rear outer surface of the inverted L bracket 15.

[0028] By adopting the above technical solution, the arc-shaped knife 16 moves through the arc-shaped transmission block 14, so that the cutting stroke is larger and the force applied is larger, so that the staff can complete the cutting work more easily.

[0029] A reset button 6 is provided on a side of the length gauge 5 away from the workbench.

[0030] By adopting the above technical solution, after each section of cable is cut, the length meter 5 can be reset to zero by pressing the reset button 6, so as to facilitate re-counting.

[0031] The workbench 2 is threadedly connected with a limit ring 3 corresponding to the height of the cable cutting groove 17. By adopting the above technical solution, the limit ring 3 can be replaced with different cable diameters, and the limit ring 3 allows the cable to pass smoothly to prevent swinging during cutting and affecting the cutting quality.

[0032] The upper roller 9 and the lower roller 8 are located in the same vertical plane, and the outer rings of the upper roller 9 and the lower roller 8 are covered with rubber.

[0033] By adopting the above technical solution, the surface friction between the upper drum 9 and the lower drum 8 is relatively large, which prevents the cable from loosening when passing through.

[0034] The lower surface of the workbench 2 has four table legs 1 distributed in a rectangular shape.

[0035] Working principle: When the utility model is in use, the staff selects a limit ring 3 of appropriate size and installs the limit ring 3 on the workbench 2 through a thread, passes the cable to be cut through the limit ring 3, and when the power cable reaches the upper roller 4 and the lower roller 3, pulls the hand pull ring 11 upward to move the upper roller 9 upward, pulls the cable through the cable cutting groove 13 in the middle of the knife groove 11, and then pulls the power cable according to the indication displayed on the length meter 5. When the indication of the length meter 5 reaches a predetermined size, stop pulling the cable, and then pull the crank pull rod 13 downward to drive the arc knife 16 to cut the cable. After the cutting is completed, press the reset button 6, clear the indication of the length meter 5 and repeat the above work until the cable cutting work is finally completed.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
